QualRSD {MixedLevelRSDs}R Documentation

Second Order RSDs with qualitative factors

Description

Generate a Second Order Design where first v-k column represent v-k quantitative factors and the last k column represents the k qualitative factors (1<=k<=v-2). It also gives D-efficiency and G-efficiency for the generated design.

Usage

QualRSD(v, k, Interaction = FALSE)

Arguments

v

Total number of input factors

k

Number of qualitative factors, 1<=k<=v-2

Interaction

To specify whether to generate a design for fitting second order model which include Interaction term between qualitative and quantitative factors. The interaction = T means the generated designs will be suitable to fit a second order model which include interaction between qualitative factors and the linear terms of quantitative factors

Value

Second Order RSDs with qualitative factors along with D-efficiency and G-efficiency
